A renewed effort is underway today to locate four-year-old Gus Lamont, who vanished nearly two months ago from his family’s secluded property in South Australia.

Starting this morning, authorities will examine six mine shafts situated in the isolated region where Gus was last observed, according to police reports.

Officials stated that these shafts were previously unknown to them.

The last sighting of Gus was around 5 p.m. on Saturday, September 27, when his grandmother spotted him playing on a dirt mound at the family’s Oak Park Station homestead, located roughly 43 kilometers from Yunta.

By 5:30 p.m., Gus—described as both shy and adventurous—had disappeared, prompting an extensive ground and aerial search of the homestead and its surroundings.

This latest search operation is scheduled to span three days.

It will involve STAR Group officers and Task Force Horizon officers using specialised equipment to search six mine shafts in the area.

The uncovered, unfenced shafts are between 5.5km and 12km from the Oak Park homestead, in areas not searched on foot by police.

Deputy Commissioner of Police Linda Williams said the new searches were part of ongoing investigations.

“We are determined to explore every avenue in an effort to locate Gus Lamont and provide some closure for his family,” she said.

“These searches will either locate evidence or eliminate these locations from further investigation by the Task Force.”

This followed extensive ground and air searches of the area surrounding the Oak Park Station homestead.

The ground search has now extended to 5.5km from the homestead.

This equates to 95sq/km searched on foot.

This area searched with the help of aircraft and mounted officers has been estimated at 470sqkm, with no sign of the child.

Police stressed that no part of the investigation had turned up any suggestion of foul play.
